I'm going though a box of random PCB's I aquired and I'm trying to identify what they all are, if they are worth keeping, if they are worth anything for selling ect. I'm not super familiar with all pinball boards so some of these might be obvious, but other ones I have noticed have strange differences between regular production boards, and some I'm just not sure on.
We'll start with board 1. I've identified it as the 8 high power PCB from twilight zone. I'm pretty sure this normally only has 5 transistors but this one is fully populated with 8
